Price Regulation of Access to Telecommunications Networks

Regulation and Investment in Network Industries: Evidence from European Telecoms

“…12 According to the so-called "investment ladder" theory (Cave and Vogelsang, 2003;Cave 2006), entrants enabled by low access fees to build up an installed base and learn about demand and cost conditions will subsequently be encouraged by rising access charges, together with technological progress and falling costs, to roll out their own networks and 11 Using US data, Allan T. Ingraham and J. Gregory Sidak (2003) present econometric evidence that supports this hypothesis. 12 See Valletti (2003) and Ingo Vogelsang (2003) for a general overview of access pricing and its possible effect on innovation and investment.…”

Network growth: Theory and evidence from the mobile telephone industry

“…An excellent summary of access pricing is provided by Vogelsang (2003). An outstanding and comprehensive overview of regulatory issues is given in Armstrong and Sappington (2005).…”

“…To begin, we assume that, for each subscriber, a constant fraction of all calls, α, are placed to mobile phones while the remaining fraction, 1 − α, are placed to fixed phones. 12 We further assume that a fraction, β, of mobile to mobile calls are terminated with a competitor's subscriber.…”

“…. 12 It is important to differentiate between the ultimate destination of a call since mobile and fixedline operators charge a different termination rate. Calzada and Valletti (2008) also investigate the impact of a variety of termination rates under the possibility of entry.…”
